I can only hope it's being set up that way (CO2 & Electric) to move a heavy bolt and make the shooting experience more visceral, like a KWC Mini Uzi on steroids.
And for anyone intimately familiar with external gas guns: could they be run off a compressor? Or do they really require bursts of very high power gas? (I'm guessing the gas is regulated, but dunno down to what pressure)
